<p>A molded body comprises a film with a film thickness D ranging from 1 mum to 1000 mum, with at least one hollow structure configured into the film. Each hollow structure has an outside diameter d equal to at least double value of film thickness D, a height h is equal to or less than double the value of the outside diameter d, a wall thickness b greater than 0.02 times the film thickness D and less than or equal to the film thickness D and a local curvature radius r greater than 0.2 times and less than or equal to 5 times the wall thickness b. The film and the hollow structure include a plurality of pores.</p> |
